I'm confused why the nozzles do not match the dryer...

After careful consideration of which hairdryer to buy (I'm picky because I hate heavy, loud hair dryers) I settled for this one. It is light weight, dries hair super quick and adds lots of shine and volume. I wouldn't say it lives up to the claim of being quiet though- it's quite loud/noisy! The only downside I've experienced and it's probably just me, it sometimes makes my fine hair fall flat and limp like it's too shiny (I know ionic hair dryers do this to me). I've tried to correct this by trying lots of different brushes/ without brushes and I still have this issue but maybe I'm using too much heat so I'll need to just get used to the settings. Oh and another point on the settings- the highest heat setting is pretty high so if you use that you need to work quickly. The medium heat setting is really good though!
